In September, about a month before Apple's cofounder died, I asserted that "Steven Sinofksy is the new Steve Jobs". Jobs' on-stage presentations, and the "reality distortion field" with them, are legendary. But chatter and buzz can fill the InterWebs, without seemingly magical Apple events. Sinofsky's blog post, "Building Windows for the ARM processor architecture", while hardly a compelling title, is Microsoft's manifesto for this decade. People are talking, chatting, buzzing -- and they should be.

Microsoft is in the process of rebuilding Windows for the post-PC era, by stepping back from its core roots -- Intel processors -- and embracing ARM. Windows will still run on x86 processors, but there's now little doubt that, without major chip changes from AMD or Intel, Wintel is legacy and ARM is the future. The architectural change opens up mobile device categories, even Windows 8 on smartphones, that the OS can't effectively reach today. Essentially, Microsoft is betting the flagship operating system's future on ARM. Sinofsky made a big statement in a small way -- nothing more than one of the longest blog posts you'll read ever (It's more than 8,000 words, closer to 9,000 really, which is enough to publish as a Kindle Single).
